limited charge with new solar cell

i have a new 160W mono crystalline solar cell

i hooked it up to my new BlueSolar MPPT 100/30 solar controller
if the slar Voltage is =< that the lion battert it wont do anything


at 17 V , i still cant get more than 0.1A about 1w output with plenty of light
the upper voltage for the panel is 24V

this what the victron colour controller shows

is this normal?
should i get more current/power out?
does the voltage need to be higher

If your batteries are fully charged then it would only have a get .1 amp going into the batteries. Is this reading before or after that Solar Controller? Run your batteries down to less than 75% and then you should see that amps jump up

BTW is this reading before or after that Solar Controller?
The reason I ask is if this is after the controller you should not be having a 17 volt reading. If before the controller this is normal voltage coming off the solar panels.

the two reading are right at the terminal going into the MPP solar controller. they are displays in the controller gui

the battery was at 93 % at the time, and i thought the the amp reading would be higher

The controller said only 10 hours left to get to 100%

Sorry I missed that you are working with a 24v panel. There can be several things wrong, the easiest being is the panel in full bright sunlight? If not wait until between noon and 1pm and check again.
The voltage should be higher but the amps will be low due to the high charge state of the batteries but not that low.

Have you checked the voltage right at the panel?
How long is your run and what is the wire gauge from the panel to the panel to the controller?

What is the programmed "charge voltage" from the controller? Voltage differential matters, if the voltage differential is small the potential for power transfer decreases.
